Title	Offsite Notification Due to Spurious Siren Activation
Event Description	TVA received notification from Tennessee Emergency Management Agency (TEMA) at 1336 Eastern Daylight Saving Time (EDT) that Rhea County 911 operators had received several calls (approximately 6) regarding a siren sounding in north Rhea County. An electronic poll of the siren closest to the location of the reporting parties (Siren 43) indicated no response, although that siren did successfully respond to the 0700 daily poll on 7/4/2011. This may indicate that this siren is not operable. A severe thunderstorm warning had been issued by the National Weather Service for the time period this potential activation was reported. During this period there were several spurious acoustic monitor alarms from three additional sirens, although there were no other indications of siren activations (e.g., rotate or timer signals). A field investigation has been initiated, and the siren will be repaired as needed in accordance with TVA's corrective action program. There was no plant event that required siren actuation, and all plant systems are operating as required. The licensee will notify the NRC Resident Inspector.
